What is Nucleoid (DNA) , ribosomes and flagellum in eubacteria?
(in a simple and veryshort explanation )
Nucleoid (DNA): In eubacteria, nucleoid is the region within the cell where the DNA is located. It is not enclosed within a nucleus and is instead found as a circular piece of DNA floating freely in the cytoplasm.
Ribosomes: Ribosomes are small structures found in the cytoplasm of eubacteria that are responsible for protein synthesis. They read the genetic information from the DNA and use it to produce proteins, which are essential for the functioning and survival of the bacteria.
Flagellum: Flagellum is a whip-like structure found in some eubacteria that allows them to move. It acts like a propeller, spinning and propelling the bacteria through liquid environments by generating a rotational motion. The flagellum helps eubacteria to migrate towards favorable conditions or move away from harmful environments.
1. Nucleoid (DNA): In eubacteria, the nucleoid is the region within the cell where the genetic material, the DNA, is located. Unlike eukaryotic cells, eubacteria do not have a distinct nucleus. Instead, their DNA is present in a single circular chromosome and is found in this nucleoid region. It controls the cell's functions and genetic traits.
2. Ribosomes: Ribosomes are small structures found within the cytoplasm of eubacteria that are responsible for protein synthesis. They are made up of RNA (ribonucleic acid) and proteins. Ribosomes help in translating the genetic information from DNA into proteins, which are essential for various cellular processes and functions.
3. Flagellum: Flagellum is a whip-like structure found on the surface of some eubacteria, which allows them to move. It helps them swim through liquid environments. The flagellum is powered by a rotary motor that propels the bacteria towards or away from certain stimuli, such as light or chemical signals. Its movement aids in the survival and colonization of eubacteria in desired environments.
